"It's not true that the United States and Iran have agreed to one-on-one talks or any meeting after the American elections," National Security Council Spokesman Tommy Vietor said in a statement released by the White House.

"It has always been our goal for sanctions to pressure Iran to come in line with its obligations," he said.

The report in The New York Times which was based on discussions with Obama administration officials, came as Iran is believed to be building a nuclear weapon and as a result is under heavy economic sanctions.
